From 5b34dbcd88251508d02e48ad9b0f9b8232a13ee0 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Thu, 29 Nov 2007 23:47:54 +0100 Subject: hwmon: (adm1026) Don't create files for missing inputs On the ADM1026, pins 27 and 28 can be used for two different functions: either temp3, or in8+in9. We should only create the sysfs files for the function that is configured, otherwise it is confusing for the user. Signed-off-by: Jean Delvare Signed-off-by: Mark M.
